The use of artificial intelligence has several advantages over other methods of studying the inside of cells, Johnson says.

Techniques that rely on genetic alteration, special dyes, or intense light, tend to change or damage the very cells a scientist is trying to study, he says. Also, those techniques rely on costly equipment that is not available in every lab.
